10D Mullach Coire nan Geur-oirean
My route from the Eas Chia-aig car park was as described in Andrew Dempster's Grahams book with a couple of exceptions. The vehicle track no longer loops round to the bothy but heads more or less due W to a new bridge at NN129885. Also there is a grassy vehicle track from NN092874 to the ridge at NN090887 which although not the most direct route, is easier going.
